Airworthiness Directives; Rolls-Royce Deutschland Ltd & Co KG Turbofan 

Engines 

AGENCY: Federal Aviation Administration (FAA), DOT. 

ACTION: Notice of proposed rulemaking (NPRM). 

SUMMARY: We propose to adopt a new airworthiness directive (AD) for certain RollsRoyce Deutschland Ltd & Co KG (RRD) BR700-710Al-10, -710A2-20, and -710C4-11 

turbofan engines. This proposed AD was prompted by a seized low-pressure turbine 

(LPT) fuel shut-offpawl carrier caused by corrosion of the pawl carrier pivot pin. This 

proposed AD would require removing the pawl carrier pivot pins, part number (PIN) 

BRR17117, from service and replacing them with parts eligible for installation. We are 

proposing this AD to prevent failure of the fuel shut-offmechanisrn, uncontained part 

release, damage to the engine, and damage to the airplane. 

DATES: We must receive comments on this proposed AD by [INSERT DATE 60 

DAYS AFTER DATE OF PUBLICATION IN THE FEDERAL REGISTER]. 

ADDRESSES: You may send comments by any of the following methods: 

• Federal eRulemaking Portal: Go to http://www.regulations.gov. Follow the 

instructions for submitting comments. 

• Mail: Docket Management Facility, U.S. Department of Transportation, 1200 

New Jersey Avenue SE., West Building Ground Floor, Room W12-140, Washington, DC 

20590-0001. 
You may examine the AD docket on the Internet at http://www.regulations.gov by 

searching for and locating Docket No. or in person at the Docket 

Operations office between 9 a.m. and 5 p.m., Monday through Friday, except Federal 

holidays. The AD docket contains this proposed AD, the mandatory continuing 

airworthiness information (MCAI), the regulatory evaluation, any comments received, 

and other information. The address for the Docket Office {phone: 800-647-5527) is in the 

ADDRESSES section. Comments will be available in the AD docket shortly after receipt.

the Member States of the European Community, has issued EASA AD 2016-0034, dated 

Febntary 24,2016 (referred to hereinafter as "the MCAI"), to correct an unsafe condition 

for the specified products. The MCAI states: 

Seizing of a fuel shut-off mechanism pawl carrier was reported. 

The subsequent investigation determined that corrosion of the pawl 

carrier pivot pin PIN BRR17117, was the failure cause. 

This condition, if not corrected, could lead to loss of the fuel shut-

(!ff mechanism functionality and loss of the engine over-speed 

protection, possibly resulting in release of high-energy debris, with 

consequent damage to, and/or reduced control of the airplane. 

You may obtain further information by examining the MCAI in the AD docket on 

the Internet at http://www.regulations.gov by searching for and locating Docket No. 

FAA-2016-4551. 

FAA's Determination and Requirements of This Proposed AD 

This product has been approved by the aviation authority of Germany, and is 

approved for operation in the United States. Pursuant to our bilateral agreement with the 

European Community, EASA has notified us of the unsafe condition described in the 

MCAI and service information referenced above. We are proposing this AD because we 

evaluated all information provided by EASA and determined the unsafe condition exists 

and is likely to exist or develop on other products of the same type design. This NPRM 

would require removing the pawl carrier pivot pin, PIN BRR17117, from service and 

replacing with a part eligible for installation. 

3 
access to it through their normal course of business or by the means identified in the 

ADDRESSES section. 

Costs of Compliance 

We estimate that this proposed AD affects 4 engines installed on airplanes of U.S. 

registry. We also estimate that it would take about 3 hours per engine to comply with this 

proposed AD. The average labor rate is $85 per hour. Required parts cost about $860 per 

engine. Based on these figures, we estimate the cost of this proposed AD on U.S. 

operators to be $4,460. 

Authority for This Rulemaking 

Title 49 of the United States Code specifies the FAA's authority to issue rules on 

aviation safety. Subtitle I, section 106, describes the authority of the FAA Administrator. 

"Subtitle VII: Aviation Programs," describes in more detail the scope of the Agency's 

authority. 

We are issuing this rulemaking under the authority described in "Subtitle VII, 

Part A, Subpart III, Section 44701: General requirements." Under that section, Congress 

charges the FAA with promoting safe flight of civil aircraft in air commerce by 

prescribing regulations for practices, methods, and procedures the Administrator finds 

necessary for safety in air commerce. This regulation is within the scope of that authority 

because it addresses an unsafe condition that is likely to exist or develop on products 

identified in this rulemaking action. 

4 
or on the distribution of power and responsibilities among the various levels of 

goverrunent. 

For the reasons discussed above, I certify this proposed regulation: 

(1) Is not a "significant regulatory action" under Executive Order 12866, 

(2) Is not a "significant rule" under the DOT Regulatory Policies and Procedures 

( 44 FR II 034, February 26, 1979), 

(3) Will not affect intrastate aviation in Alaska to the extent that it justifies 

making a regulatory distinction, and 

( 4) Will not have a significant economic impact, positive or negative, on a 

substantial number of small entities under the criteria of the Regulatory Flexibility Act. 

List of Subjects in 14 CFR Part 39 

Air transportation, Aircraft, Aviation safety, Incorporation by reference, Safety. 

The Proposed Amendment 

Accordingly, under the authority delegated to me by the Administrator, the FAA 

proposes to amend 14 CFR part 39 as follows:
